Ec2.ClientVpnEndpoint: Tags do not get applied to the created client VPN endpoint

### Describe the bug

This is essentially a re-opening I believe of https://github.com/aws/aws-cdk/issues/18381.

I found this when using CDK to create a Client VPN endpoint. I used Tags.Of(endpoint).Add() - and the tag was added to the AWS:Logs:LogGroup that gets created, but not to the client VPN endpoint.

### Last Known Working CDK Version

_No response_

### Expected Behavior

The Client VPN Endpoint gets created with specified tag applied to it.

### Current Behavior

The CDK deploy succeeds, however, the Client VPN Endpoint does not have a tag. The LogGroup it creates automatically did get the tag - it is not clear to me if that is intended/desired or not.

### Reproduction Steps

C#

```
ClientVpnEndpoint endpoint = new ClientVpnEndpoint(this, name, new ClientVpnEndpointProps
{
AuthorizeAllUsersToVpcCidr = false,
Cidr = cidr,
ServerCertificateArn = certArn
UserBasedAuthentication = ClientVpnUserBasedAuthentication.Federated(samlProvider),
TransportProtocol = TransportProtocol.TCP,
Vpc = vpc,
Port = VpnPort.HTTPS,
SessionTimeout = ClientVpnSessionTimeout.TWELVE_HOURS,
SecurityGroups = new [] { securityGroup },
SplitTunnel = true,
VpcSubnets = new SubnetSelection{ Subnets = privateSubnets },
});

Amazon.CDK.Tags.Of(endpoint).Add("Name", name);
```

### Possible Solution

_No response_

### Additional Information/Context

Specifically, I was trying to apply a name to the Client VPN Endpoint. Based on the AWS console in the browser, this appears to occur not via a Name property on the endpoint, but through a tag named "Name". But as noted above, the loggroup picked up the tag, but not the endpoint. The endpoint displayed a blank value in the AWS console for the Name column.

Manually adding a "Name" tag to the endpoint through the browser filled in the Name column as desired.

### Other information

Start at the ClientVpnEndpoint construct and its tag application path, using the C# reproduction in the issue as the entry point. Inspect the synthesized or deployed resource and compare it with the automatically created LogGroup. Done means Tags.Of(endpoint).Add("Name", name) applies the tag to the Client VPN endpoint as well as preserving the expected LogGroup behavior.
